<br />' approximately 3400 feet. (Please refer to the Reclamation Plan Map <br />where this is depicted.) <br />' It is estimated that there is overburden soil enough to fill <br />approximately 28 acres of the mined area. <br />' The deposit will be excavated to an average depth of 23 feet, of <br />which an average 16 feet is gravel and 6 feet is overburden soil. <br />Excavation will be conducted to produce a 1:1 slope. This slope <br />' will then be filled and graded to a 3:1 slope for final <br />reclamation. Backfilling and initial grading of slopes will be <br />done concurrently with the mining process. <br />' It is anticipated that the life of the mine will be 8 to 10 years, <br />based on current market situations. <br />' Underground water is present at approximately 12 feet below <br />existing ground level. This will result in the creation of a water <br />impoundment in the form of a lake approximately 48 acres in size. <br />As depicted on the Premining Nap, there is a drainage easement in <br />the western portion of the site. This easement is now provided <br /> with a paved structure to sheet-flow storm water across the site. <br />' This paved structure will remain intact until mining reaches that <br /> point. At this time the existing structure will be removed and an <br /> alternate structure will be constructed to direct storm water into <br />' the excavated area where it will be retained until it dissipates by <br /> evaporation or percolation. The alternate storm water collection <br /> structure will remain as a permanent part of the reclaimed site. <br />' Please refer to the Reclamation Plan Map, where this structure is <br />depicted. An inlet and an outlet will be provided, however it is <br />not expected that the outlet will ever be needed because of the <br />small amount of precipitation that is received in this vicinity. <br />Also depicted on the Premining Map is a access road into the <br />' Division of Wildlife property at the west end of the site. The <br />Division of Wildlife has agreed to a plan that will relocate this <br />road to the extreme west perimeter of the subject property. The <br />existing road will remain intact until such time that it becomes <br />' necessary or feasible to remove the existing road and construct the <br />new one. United Companies has committed to bear the responsibility <br />and the costs to accomplish this procedure. The reconstructed road <br />' will be within a dedicated easement, 50 feet wide, and will be <br />constructed to meet or exceed the standards of the existing road. <br />1 <br /> <br />' 4 <br /> <br />
